Abstract

Non-destructive techniques for the demonstration of chemical changes in the rhizosphere of soil-grown plants are described. The following processes are demonstrated: FeIII reduction indicated by the formation of a red coloured complex between Fell and bathophenanthroline-disulfonate (BPDS) in an agar medium; MnIV reduction indicated by the decolourization of filter paper impregnated with Mn oxide; complexation of Alby the decolourization of polyacrylamide gel or agar containing Al and aluminon; and the activity of acid phosphatase indicated by the formation of a red complex on filter paper containing l-naphthyl phosphateas substrate and Fast Red TR as an indicator.
